Mrs Martini age is 42 years and Tony age is 12 years
Step-by-step explanation:
The given is:
Mrs. Martini is 6 years more than 3 times as old as TonyEight years ago, she was 2 years less than 9 times as old as he was thenAssume that Tony is x years old now
∵ Mrs. Martini is 6 years more than 3 times as old as Tony
∵ Tony is x years old
- Multiply the age of Tony by 3 and add 6 to the product
∴ The age of Mrs Martini = 3 x + 6
8 years ago
- Subtract 8 from the age of each one
Tony age = (x - 8)
Mrs Martini age = (3 x + 6) - 8 = 3 x + 6 - 8 = 3 x - 2
∵ Eight years ago, Mrs Martini was 2 years less than 9 times as old
as Tony was then
- Multiply Tony age by 9 and subtract 2 from the product
∵ Tony age from 8 years ago = x - 8
∵ Mrs Martini age from 8 years ago = 3 x - 2
∴ 9(x - 8) - 2 = 3 x - 2
- Simplify the left hand side
∴ 9 x - 72 - 2 = 3 x - 2
- Add like terms
∴ 9 x - 74 = 3 x - 2
- Subtract 3 x from both sides
∴ 6 x - 74 = -2
- Add 74 to both sides
∴ 6 x = 72
- Divide both sides by 6
∴ x = 12
∵ x represents the age of Tony
∴ Tony is 12 years old
∴ 3 x + 6 is the age of Mrs Martini
- Substitute x by 12
∵ 3(12) + 6 = 36 + 6 = 42
∴ Mrs Martini is 42 years old
Mrs Martini age is 42 years and Tony age is 12 years

The relationship between number of animals owned and the number of vet bills is an example of what type of correlation
Answer:
The relationship between number of animals owned and the number of vet bills is an example positive correlation.
Step-by-step explanation:
Correlation:
Correlation is a technique that help us to find or define a relationship between two variables. It is a measure of linear relationship between two quantities. A positive correlation means that an increase in one quantity leads to an increase in another quantity A negative correlation means with increase in one quantity the other quantity decreases. +1 tells about a a perfect positive linear relationship and −1 indicates a perfect negative linear relationship.Now, as the number of animals increase the number of vet bills will increase. Thus, it could be said that increase in one variable leads to increase in another variable.
Thus, the given relationship is an example of positive relationship or a positive correlation.
AB contains points (2, 1) and (-1, -8). What is the equation of the line parallel to AB that contains point (0, 2)?
For this case we have that by definition, the equation of a line in the slope-intersection form is given by:
[tex]y = mx + b[/tex]
Where:
m: It's the slope
b: It is the cut-off point with the y axis
We have two points that belong to the AB line:
[tex](x_ {1}, y_ {1}) :( 2,1)\\(x_ {2}, y_ {2}): (- 1, -8)[/tex]
We can find the slope:
[tex]m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}} = \frac {-8-1} {- 1-2} = \frac {-9} {- 3} = 3[/tex]
By definition, if two lines are parallel then their slopes are equal. Thus, a line parallel to AB will have slope [tex]m = 3[/tex], then the equation will be of the form:
[tex]y = 3x + b[/tex]
We substitute the given point and find b:
[tex](x, y) :( 0,2)\\2 = 3 (0) + b\\2 = b[/tex]
Finally, the equation is:
[tex]y = 3x + 2[/tex]
Answer:
[tex]y = 3x + 2[/tex]

A table measures 3 feet across. How many inches is this?
My Answer-36
Answer:
The corresponding answers to the questions are 9.625 cm² , 459, 304.5m², 1 : 3 , 3:4 , 10,000 pounds , 36 inches.
Step-by-step explanation:
1.
Area of triangle = 0.5 x base length x height
Here base length = 5.5cm and height = 3.5cm
So area will be 0.5 x 5.5 x 3.5 cm² = 9.625 cm²
2.
919/2 rounding off to nearest whole
We know that the value of 919/2 = 459.5 .
So the nearest whole number value to which it can be rounded off is 459.
3.
We know that area of parallelogram is base length x height
Here, base length =14.5m and height = 21m
So area = 14.5 x 21 m² = 304.5m²
4.
No. of grilled cheese sandwiches sold = 200
No. of tacos sold = 100
No. of grilled chicken salads sold = 150
Total lunches sold = 200 + 100 + 150 = 450
So, ratio of chicken salads to lunches sold is 150 : 450 = 1 : 3
5.
Given number : 7,208,631
Odd digits here - 7,3,1 - 3 digits
Even digits here - 2,0,8,6 - 4 digits
So, ratio of odd digits to even digits is 3:4
6.
One ton = 2000 pounds
So 5 tons = 5 x ( 1 ton) = 5 x 2000 pounds = 10,000 pounds
7.

You work 37 1/2 hours and earn $352.50. What is your hourly wage
Answer:
$9.40
Step-by-step explanation:
well since you work 37.5 hours and you earn $352.50 you divide them to get your hourly wage
352.5 ÷ 37.5 = 9.4
so your hourly wage is $9.40
Final answer:
To calculate the hourly wage, the total earnings of $352.50 should be divided by the total work hours of 37.5. The hourly wage comes out to be $9.40.
Explanation:
To find out your hourly wage, you need to divide your total earnings by the number of work hours. In this instance, you worked 37.5 hours (since 1/2 an hour is equivalent to 0.5 hours) and earned $352.50. So, your hourly wage would be calculated as follows:
Hourly Wage = Total Earnings ÷ Number of Work Hours
Hourly Wage = $352.50 ÷ 37.5 hours
Hourly Wage = $9.40 per hour
Therefore, your hourly wage is $9.40.
In order to play at the Cape Gerbil City Miniature Golf Club, a player has to pay the membership fee and pay for each round played. The total cost is represented by the function
T = 33.47r + 17.72, where T = the total cost (in dollars) and r = the number of rounds played.
Which of the following statements must be true?
A .The slope is the cost per round $33.47, and the y-intercept is the membership fee of $17.72.
B.The total cost is $51.19.
C.The slope is the cost per round $17.72, and the y-intercept is the membership fee of $33.47.
D.The slope is the membership fee of $17.72, and the y-intercept is the number of rounds played.
E.I don't know
Please answer
Final answer:
The correct statement must be that the slope of the equation is the cost per round of $33.47, and the y-intercept is the initial membership fee of $17.72, since the slope represents the additional cost per round and the y-intercept the initial cost at zero rounds.
Explanation:
In the function T = 33.47r + 17.72, which represents the total cost T of playing miniature golf as a function of the number of rounds played r, the coefficient of r represents the slope and the constant term is the y-intercept. The slope indicates the additional cost for each additional round of golf played, while the y-intercept represents the initial cost when no rounds are played, which can be interpreted as the membership fee. Therefore, the correct statement about the cost structure of the Cape Gerbil City Miniature Golf Club is A: The slope is the cost per round $33.47, and the y-intercept is the membership fee of $17.72.

Cells store energy in the form ATPs. These molecules power al the biochemical activities that would not occur spontaneously. Examples of these bioactivities are the contraction of actin filaments, glycolysis cycle, replication of DNA, cell division, gene expression, cell repair and etcetera.
Step-by-step explanation:
All ATPs are not spent at the same time, and futhermore, they are constantly replaced by the continuous process of cellular respiration that captures the chemical energy in the glucose molecules and stores them in ATP. During the release of this energy to power the biochemical reactions, much of it is lost as heat energy and this is why living organisms are always warm.

Using the approximation 3.14 for \pi what is the radius of a circle with circumference 75.4m
Answer:
The radius of the circle is 12.006 m.
Step-by-step explanation:
Let us assume the radius of the circle = r
Circumference = 75.4 m
Now, CIRCUMFERENCE OF A CIRCLE = 2 π r
⇒ 75 .4 m = 2 π r
Now, putting π = 3.14, we get:
75 .4 m = 2 (3.14) r
⇒ 75.4 = 6. 28 r
or, r = 75.4/6.28 = 12.006
or, r = 12.006 m
Hence, the radius of the circle with circumference 75.4 m is 12.006 m.

Hey circular trampoline has an area of 132.2 ft.² what is the radius of the trampoline rounded to the nearest tenth
Final answer:
To find the radius of the circular trampoline, we can use the formula for the area of a circle and rearrange it to solve for the radius. The radius of the trampoline is approximately 6.5 ft (rounded to the nearest tenth).
Explanation:
To find the radius of the circular trampoline, we can use the formula for the area of a circle, which is A = πr². In this case, the area is given as 132.2 ft². We can rearrange the formula to solve for the radius:
r² = A/π
r² = 132.2/π
r ≈ √(132.2/π)
r ≈ √(42)
r ≈ 6.5 ft (rounded to the nearest tenth)
Final answer:
To find the radius of the trampoline, we use the formula for the area of a circle and rearrange it to solve for the radius. After substituting the given area and approximating π as 3.14, we find that the radius is approximately 6.5 ft when rounded to the nearest tenth.
Explanation:
The area of a circle is given by the formula A = πr², where A is the area and r is the radius of the circle. Given the area of the trampoline as 132.2 ft², we can solve for the radius using the area formula. We rearrange the formula to solve for the radius: r = √(A/π).
Substituting the given area and the approximate value for π (3.14), we get r = √(132.2/3.14). This simplifies to r = √(42.085...), which is approximately r = 6.487 ft. Rounding to the nearest tenth gives us a radius of 6.5 ft.

Given A(5,3) and O(0,0), find a point B that makes the following true: m(A,B)=3
A point B is (1 , -9)
Step-by-step explanation:
The formula of the slope of a line is [tex]m=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
where [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex] are two points
lie on the line
A (5 , 3) and O (0 , 0) are two pointsm(A , B) = 3 ⇒ (the slope of AB = 3)We need to find a point B that makes that true
Assume that point B is (x , y)
∵ Point A = (5 , 3)
∵ Point B = (x , y)
∴ [tex]x_{1}=5[/tex] and [tex]x_{2}=x[/tex]
∴ [tex]y_{1}=3[/tex] and [tex]y_{2}=y[/tex]
- Substitute these values in the formula of m
∴ [tex]m=\frac{y-3}{x-5}[/tex]
∵ m(A , B) = 3
- Equate the formula of the slope by 3
∴ [tex]\frac{y-3}{x-5}=3[/tex]
- By using cross multiplication
∴ y - 3 = 3(x - 5)
- Simplify the right hand side
∴ y - 3 = 3x - 15
- Add 3 for both sides
∴ y = 3x - 12
To find point B chose any value for x and substitute it in the
equation to find y
∵ x = 1
∴ y = 3(1) - 12 = 3 - 12
∴ y = 9
∴ Point B = (1 , -9)
V.I.N: You can find many values of point B by chose different values of x and find the corresponding values of y
A point B is (1 , -9)

So you would divide 737 (miles) by 11 (hours) in order to find how far he traveled in 1 hour. You should get 67. So he travels at 67 miles in 1 hour. Then you would divide 871(total miles) by 67(distance traveled in 1 hour) to find out how many hours it took to travel 871. You should get 13(hours).
Hoped it helped.
Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar. The function below represents the monthly expenses for an event planning company where f(x) represents the total monthly expenses for planning x events. If at the end of one month the expenses for the company were $12,350, then ___ events were planned
f(x) = 50(2x=1) + 300
Answer:
There were 120 events planned.
Step-by-step explanation:
We are given the following information in the question:
f(x) represents the total monthly expenses for planning x events.
[tex]f(x) = 50(2x+1) + 300[/tex]
Cost of expenses for the company at the end of one month = $12,350
We have to find the number of events planned that is we have to find the value of x.
[tex]f(x) = 50(2x+1) + 300 = 12350\\50(2x+1) + 300 = 12350\\100x + 50 + 300 = 12350\\100x + 350 = 12350\\100x = 12350-350\\100x = 12000\\\\x = \displaystyle\frac{12000}{100} =120[/tex]
Thus, there were 120 events planned.
